Application led'ebruary 12, 191.6. Serial No. 77,818.

To all whom it may Concern: g Fig. 4 is a view similar to Fig. 1,showing Be it known that I, CARL G. PRrroHARD, a a modied embodiment ofmy invention;

citizen of the United States, and a resident Fig. is a view similar toFig. 4, with the of Warren, in the county of Trumbull andtransfer-cylinder separated from the form- Lao 5 State of Ohio, haveinvented certain new and useful Improvements in Printing Presses, o-fwhich the following is a specification.

My invention relates to printing-presses, and the yinvention isIembodied in improvements for separating the printing or other coactingmembers of the press, and also in improved devices for throwing oif theinking rollers in such a printing-press, controlled but not operated bythe mechanism devised for the throwing olf of l`the 'impression, andalso in any such predetermined relation therewith, as may be desired.

The objects of my invention are, among `other things, to provide a pressof this general character of a simple and efficient construction,whereby the means devised for separating the printing members and forthrowing of the inking rollers may be controlled and actuated, eitherindependently of the impression throw-off, or by automatic mechanismoperated by the further Inovement or rotation of the press in its normaloperation after the initial throw-off.

My improved construction also vpresents other features of novelty andusefulness whereby the operating mechanism is rendered stronger and more.durable and otherwise better adapted and more convenient for use, allof which will be hereinafter set forth and claimed.

The accompanying l herein, and forming a part thereof, show severalembodiments of -the invention in 0E-set presses, the same serving, inconnection with the description herein, to fully explain the invention,which is not-restricted, however, to any particular form or type ofprinting-press construction. v

Similar numerals refer tofsimilar parts throughout the several figures.

Referring-more particularly to 3the embodiment shown in Figs. 1, 2 and3, the frame 12 `supports the bearings for the form-cylinder 13, thetransfer-cylinder 14 and the impression-cylinder 15, said cylindersbeing mounted on the shafts 16, 17 and 18 respectively.'` The cylindersare so constructed and arranged in the frame 12 that thetransfer-cylinder 14 forming the printing couple with theimpression-cylinder 15, receives its design from the form-cylinder 13.The form, transfer and impression cylinders have each` fastened theretosuitable gears whose pitch-diameter coincides withthe periphery of therespective cylinders. These gears intermesh and form the drivingmechanism to secure proper rotaxtion for the cylinders. rllhe power isderived fromthe usual pulley shaft, which is connected to the Icylindergears by a compound gear train. Since these are common forms ofprintingpress construction vand are well known in the art, they arenot'shown in the drawings.

The shaft 17 carrying the transfer-cylinder 14 is mounted at vboth endsin the eccentric bearings 19, which, in turn, are mounted in thejournals 20a secured tothe frame 12.

' as shown on one side thereof. The togglev projecting llhe bearings 19have arms 20 frame 12,

from Hanges on the outside of the levers 21 and 22 connect the outer endo f the arm to the frame, the lever 21 being Journaled to the outer endof the arm 20, while the lever 22 is pivoted to the frame aty 23.

apo

. the interposition of the stock 37 nates the feed-table and -shaft 38which The coil spring 24 connects the arm 21 to the frame 12, as shown,the spring bein .Strained when the y'toggle is straightene to the outerend of the lever 22 25, the other end of which is pivoted to the arm 26mounted on the oscillating shaft 27, which may ybe actuated by thespring 24, or through a coil spring (not shown) mounted upon The handlever 28 carrying the lug 29 is arranged to co-act with the lug 30secured -to the shaft 27 to restore the impression.

rlhe shaft 27 is held in the position shown in Fig. 1 by the latch 31pivoted on the shaft 32 in the bracket 33, which latch 31 engages anotch 34 in the sleeve 35 mounted on the shaft 27, as shown in detail inFigs. 10 and 11. Preferably this latch 31 would be releasedautomatically through the trip mechanism on the feeder, which isparticularly shown in Figs. 10, and 11. AIn these views, 36 desig- 37 isthe stock that 1s being fed to the press. Extending transversely abovethe feed-table 36 and journaled to uprights on the sides thereof, is thecarries the arm 38 (Fig. 1 0) connected by the rod 39 to the shaft 18ofthe impression-cylinder 15 by any suitable means, so as to impart tothe shaft 38 an oscillating movement. 40, 40 indicate grooved collarsrigidly secured to the shaft 38. Adjacent each grooved collar 40 is thedisk 41 aHXed tothe end of the tubular shaft 42 which is looselysleevedon, and incloses a portion of, the shaft 38, as shown in Fig. 11.he shaft 42 carries the arm 43, the outer end of which engages with thearm 44 mounted on the block; 45 secured to the shaft 32.

' 46 indicates the trip-leverpivoted at 47 between the parallel sides ofthe grooved collars 40, so that its longer and heavier arm is held fromfalling into the aperture 48 cut in the top of the feed-table 36 by asshown in Figs. ,10 and 11. At the opposite end the lever 46 is T-shaped.to form the tooth 49, and in the peripheries of the sidesfof the collar40, and also in the periphery of the disk 41, vare formed cut-outs 50and 51 respectively. Ordinarily .the tooth 49 rests against, or is inproximity to, the periphery 0f the disk 41; it can en age with thecutout 50 of the collar 40 on y when it can fall into the cut-out 51 ofthe disk 41. this occurs, the disk 41 with its shaft 42, which arenormally at rest, are locked to the shaft 27 itself.,

When

and turn ywith theoscillating shaft 38. The entrance of this tooth 49into locking engagement with thedisk 41 will occur upon the failure orinterruption in the feed supply. When thestock 37 is in proper position,as shown in Figs. 10 and 1l, the curved longer arm of the trip-lever 46will engage therewith and willbe prevented from lower-v ing into theaperture 48, and from turning suflciently to interlock with the disk 41.lf the stock 37 should, at any time, be interrupted or absent, thelonger arm of the triplever 46 will fall of its own weight, into theaperture 48, thereby causing the tooth 49 to interlock with the cut-out51 in the disk. Thus the tubular shaft 42 will be caused to oscillatewith the shaft 38 so as to cause the arm 43 to lift the arm 44 torelease the latch 31 engaging the notch 34 in the sleeve 35 on the shaft27. Through this movement of this herein described mechanisms, thespring-impelled shaft 27 is partially rotated to swing the eccentricbearing' 19 to throw off the impression by separating the transfercylinder 14, from the formfcylinder 13 and impression-cylinder as shownin Fig. 2, all controlled automatically by the stock.

designate a series of inking rollers mounted upon a series of transverseshafts 53 carried inthe slotted bearings 54. Each inking roller 52 has acylindrical bearing 55,

concentric with its shaft 53, adapted to he4 engaged by suitably shapedcam-surfaces 56 formed in the upper portion of the rocking cam 57loosely mounted on the shaft 16 of the form-cylinder 13, the bearingsriding upon the high part of the cam 57 to lift the inking rollers fromthe form-cylinder 13, as shown in Fig. 3. The rocking movement of thecam 57 is accomplished hy the following mechanism: 58 indicates arockleverpivoted at 59 to the frame 12, so constructed and. arrangedthat. its outer end 60 may be pushed downwardly by the lug 6l preferablymounted on the 'periphery of the transfer-cylinder 14 throughtherotation of this cylinder when separated; from thepform and transfercylinder', as shown in Fig. 2, whenever the throw-off of the impressionoccurs. When the three cylinders are ineprinting relation, as shown. inFig. l, the path of rotating lug -61 will besuch as to avoid engagingwith the end 60 of the lever 58. Instead of being .axed to the peripheryvof ,the cylinder 14, the lug 61 may be mounted on the cylinder shaft17, or on the cylinder gear, either inside or outside `the frame 12.'Howeveig its location upon the transfer-cylinder itself, as shown, ispreferably the most convenient arrangement in press construction. Theopposite en d 62 of the lever 58 is connected by the link 63 with thelever 64 pivoted at 65 in the frame 12, the outer arm 66` of which formsa latch in conjunction with the notch 4o v liquely in `its eccentricbearings 19 away 67 in the collar 68 mounted on the shaft 69, journaledin the frame 12, which shaft 69 is adapted to be partially rotatedupon," the release of the latch- 66 through a coil'i` spring 70, one endof which is secured tothe outer end of thearm 71 mounted on the shaft69, and the other end to the pin v72 in the frame 12. Other suitablemeans 'for securing a partial rotation of the shaft 69 may be utilizedsuch as the usual spring coiled about the shaft itself. The flange 73secured to the cam 57 carries a pin 74 which engages and co-acts withthe socket 75 formed in the outer end of the arm 71, as shown. The coilspring'76 secured to a lug 77 onthe link 63, and also to the pin 78 inthe' frame 12, serves to hold the latch 66 in engagement with the notch67, until this latch is released by the. engagement of the rotating lug61 with the arm 60,' as shown in Fig. 3. 1f desired, thehand-lever- 79mounted on the shaft 69 may be used as a means for re-setting this shaft69`by the engagement of the latch 66 with the notch 67 in the collar 68,the lug 8O on the handle -7 9 co-acting with the lug 81 mounted on thecollar 68 to accomplish this purpose.

The operation of the hereinbefore described 'me'chanism is substantiallyas foll lows: Whenever the stock 37 is interrupted .or is absent fromthe feed table, the triplever 46 acts to release the latch 31 whichcauses a partial rotation of the spring-impelled shaft 27, the arm 26movingto the right, as shown in Fig. 2, which breaks the toggle-levers21 an-d22 through the link connection 2.5. Thebreaking of this toggleconnection immediately causes the arm 20. to swing upwardly, as shown inFig. 2, which causes the transfer-cylinder 14 to move obfrom bothform-cylinder 13 and impressioncylinder 15, thereby breaking theprinting relation of the three cylinders, `and throwing 0H the impreion,all as shown in Fig. 2. 1t will be noted from' the action ofthe press asshown in Fig. 2, that While the impression throw-off has rtaken place,the inking rollers 52 have not as yet been tripped to throw same fromthe form-cylinder 13, the lug 61 being about to engage the outer end ofthe rock-.lever 58. As the transfercylinder 14 continues its clock-wiserotation in the rotation of the press, the lug 61 through its engagementwith the end 60, rocks the lever 58 which, through the link ,63, rocksthe lever 64 to release the latch 66 from its engagement with the notch67 formed in the collar 68. The sha-ft 69 is then partially rotated in aclock-wise direction through the action of the coil sp-ring 7 0 actingon the outer end of the arm 71 mounted on the shaft, and lifts theflange 73 secured to the cam 57, causing the latter to rock on 55 theform-cylinder shaft 16 toward the left,

whereby the inking rollers 52 are lifted from the form-cylinder' 13through the roller bearings 55 riding upwardly onthe high part of thecam-surfaces 56 in -the cam 57, all as shown in Fig. 3. The hand-lever28 is lifted to restore the printing relation of the cylinders and theengagement of the latch 31 with.

the notch 34, and in like manner the handlever 79 is raised to resetfthe latch 66, whereby the outer end 60 of the rock-lever 58 is loweredbeyond the path of the lug 61, as

the transfer-cylinder is rotated, as shown by the arrows, when printingrel-ation is restored. a

It is obvious from the construction and operation of' this mechanism, asherein shown and described, that the inking rollers may be thrown offfrom the form-cylinder -b pi-Tession throw-olf, and also by meansautomatically operated through the continued movement of the press.

In the embodiment of my invention illustrated in Figs. 4, 5 and 6, lemploy the same mechanism for throwing olf the inking rollers 52, as hasbeen shown and described with reference to the embodiment illustrated inFigs. 1, 2 .and 3, but the modification is made .in the constructionutilized for accomplishing the throw-olf of the transfer cylinder 14.Fig. 4 shows all three cylinders in contact; Fig. 5 shows thetransfer-cylinder 14 separated from the form-cylinder` 13, but remainingin contact with the impression-cylinder kder 14 separated from all threecylinders and the inking rollers out of contact with the forni-cylinder13. This arrangement first separates the form-cylinder 13 andtransfercylinder 14 to prevent inking the blanket on thetransfer-cylinder, and subsequently the printing impression and theinking rollers are thrown ofi'. l

Referring to the construction shown in Figs. 4, 5 and 6, the shaft 17 ofthe transfercylinder 14 is mounted in the eccentric bearings 19. rlheshaft 17' is also mounted in the journal-'box 82-mounted to slideradially on the ways 83 in the frame 12 to and from theimpression-cylinder 15. `The compression spring 84 is secured in theopening 85 formedv in 4the frame 12 to normally force lthe journal-box82 outwardly, so as to'separate the transfer-cylinder 14 from theimpression cylinder 15. 'The transfer-cylinder 14 is held in 'contactwith the im ressioncylinder 15 against the tension of t e spring 84 bythe following mechanism: Pivoted at 85 to the frame 12 is the rock-lever86, the outer end 87 of which is arranged to be engagecl` by therotating lug 88 mounted on the cylinder 14, in the saine manner as therotating lug 61 so as t0 engage the outer end 87 of the rock-lever 86through the rotation of nthe transfer-cylinder 14 when it is separated15; and Fig. 6 shows the cylin-y when the latch 89 is in from theform-cylinder13, as shown in Figs. 5 and 6. The opposite end 89 of therocklever 86 constitutes a latch which engages in a notch 90 formed inthe collar 91 mounted on the oscillating shaft 92 journaled in the frame12. Secured to the shaft 92 is the arm 93 to which is fastened the'coilspring 94, attached to the frame 12v by the pin 95. The arm 93 ispivotally connected at 95a with the arm 96- journaled in the bracket 97carried on the journal-box 82, the arms 93 and 96 forming a straighttoggle connection between the journal-box 82 and .the shaft 92 lockingengagement with the notch 90, the spring -94 being strained. The spring98 acts to normally hold the latch 89 in engagement with the notch 90.

When the cylinders are inf. the position shown in Fig. 5, through themovement of the eccentric bearings 19, which separates thetransfer-cylinder 14 from the form- .cylinder 13, as hereinbefore shownand described, the further rotation of thetransfercylinder carries thelug 88 by the outer end 60 and' engages the end 87 of the rock-lever 86,since the arrangement is such that the lug 88 engages witlrthe arm 87only when the cylinders 13 and 14 are separated, the cylinders 14 and 15being in contact, as shown in Fig. 5; the lug 61 engages the arm 60 whenall three cylinders are separated, as shown in Fig. 6. Thecontinued'rotation of the transfer-cylinder 14 forces the end 87downwardly and rocks the lever 86 so as to release the latch 89 from thenotch 90. This release of the latch 89 causes the shaft 92 to partiallyrotate contra-clockwise through the pulling action of the coil spring94, thereby breaking the toggle connection between the shaft 92 box 82,as shown in Fig. 6, enabling the outward force of the compressed spring84 to immediately move' the transfer-cylinder 14 radially away from theimpression-cylinder 15 and to throw o" the impression; Meanwhile the lug61, contacting with the arm 60 of the rock-lever 58, has tripped thelatch 66 to throw oli the inking rolls as has been already set forthwhen describing the construction shown in Figs. 1, 2 and 3. Therefore,to conclude the cycle of operations, Fig. 6 illustrates this modifiedembodiment with the three cylinders" all separated and' the inkingrollers 52 out of contact with the form-cylinder 13, the interruption inthe feed of the stock having inaugurated the action of the mechanism tothrow oli? the transfer-cylinder from the form-cylinder 13. The latch 89is reset with its engaging notch 90 by the hand-lever 99 carrying thelug 100 coacting with vthe lug 101 on the collar 102, mounted on theshaft 102. The collar 102 carries the ar'm 103 connected by the link 104to the arm 105, mounted on the shaft 92.

and the sliding journal- When the hand-lever 99 is raised to move thearm 103 to the left, the shaft 92 is partially rotated in a clockwisedirection, to reset the latch 89 in the notch 90, when the lockingengagement is thereafter preserved through the action of the coil spring98 pulling the lever 86 to the right, slightly outside the path of thelug 88. i

By properly positioning the lugs 61-and 88 on the cylinder 14, thesuccessive tripping operations, because of their respective engagementswith the rock-levers 58 and 86, through the bodily displacement of thecylinder 14, as before described, can be timed at any intervals desiredand' in either succession. Furthermore, the position of the lug 61 issuch as to accomplish the throwing ofi' of the ink rolls 52, when theyare clear of the plate on the form-cylinder 13, thereby securing uniforminking of the entire printing surfaces of the plates.

1n the modified embodiment of my invention, illustrated in Figs. 7 and8, the transfer-cylinder 14 moves obliquely away from the form-cylinder13, and the impressioncylinder 15 has a right-angled movement away fromthe transfer-cylinder 14. l employ the same mechanism for throwing ott'the inking rollers 52, as has been heretofore shown and described withreference to the former constructions illustrated inthe precedingiigures. In the embodiment shown in Figs. 4, 5 and 6, thetransfer-cylinder 14 had two movements at substantially right angleswith each other, so as to break oli the printing relation of the threecylinders, one from the form-cylinder 13, and the other away from theimpression-cylinder f5.' Ylin the present embodiment, as shown in Figs.7 and 8, another construction and arrangement is illustrated, in whichvthe transfercylinder 14 has only a single radial movement, controlledby the sheet, away from thef throw-ofi'l movement is accomplished bymoving the impression cylinder 15, its shaft 18 being mounted .ineccentric bearings, as shown in these gures.

Referring to this modified form of oonstruction, as shown in Figs.`7`and 8, the shaft 17 of the transfe -cylinder 14 is mounted in thejournal-box 106 to'slide radially in the ways 107'formed in the frame12, at substantially right angles to the ways 83 shown in Figs. 4, 5 and6. This permits a separating movement between the cylinders 13 and 14without destroying the latters contact with the impression-cylinder 15.The coil compression spring 108 is secured in the opening 109 in theframe to normally force'the journal-box 106 outwardly, so asvto separatethe cylinder 14 from the cylinder Y -cylind'er 15, while the second orimpression I. the spring 116, which tact with the form-cylinder 13 bythe stockcontrolled tripping and latch mechanism herein described inconnection with the construction shown in Figs. 1, 2 and 3, and need notbe again described in detail. The journal-box 106 carries the bracket110 formed on its lower end, which supports the togglelevers 111 and112, the lever 112 being pivoted to the pin 113 aiiXed to the frame 12,as shown. Likewise -pivoted to the pin 113 and mounted at substantiallyright angles to the lever 112, is the arm 114 connected by the link 115to the arm 26 on the oscillating shaft 27,' the construction andoperation of which has lbeen heretofore described. rlhe coil spring 116,connecting the arm 114 to the frame, is strained when the toggle-levers111 and 112 are in their straightened position, as shown in Fig. 7. Whenthe trippingy mechanism shown in detail in, Figs. 10 and 11,` releasesthe latch 31, the link 115 is moved upwardly in the direction of thearrow shown in Fig. 7, through the force of likewise breaks thetoggle-levers 111 and 112, thereby enabling the compression spring 108to immediately movethe sliding journal-box 106 downwardly, whichmovement will, at once, separate the transfer-cylinder 14 from theformcylin'der 13,`as clearlyv shown in Fig. 8.

The' mechanism for throwing off the inking-rollers 52-in this form ofconstruction (Figs. 7 and 8), after the second or impression throwv offis accomplished, is substantially the samein construction and mode ofoperation as that shown and. described in connection with the embodimentillustrated in Figs. 1, 2 and 3, the spring 117, connected to the arm 62of the rock-lever 58 and to the frame 12, serving to hol-d the latch 66in locked engagement with the notch 67 in lieu of the spring 76, asshown in Figs. 1, 2 and 3. "The mechanism for accomplishing the second,or impression throw-off, whereby the impression-cylinder 1'5 isobliquely swung away and separated from the transfer-cylinder 14, is asfollows: The shaft 18 carrying the impression-cylinder 15 is mounted ineccentric bearings 118, which, in turn, are mounted in journals 119secured to the frame 12. The bearings 118 have arms-120 projecting fromflanges on the outside of the frame, as shofwn.. The toggle levers 121and 122, pivoted at 123, connect the arm 120 with the oscillating shaft124. The coil spring 125 connects the toggle lever 121 to the frame,this spring being strained when the toggle levers 121 and 122 arestraightened, as shown in Figs. 7 and 8.. Pivoted at 126 to the lever122 is the link 127, which affords `a rigid connection from the lever122 to the arm 128, secured on the oscillating shaft 129, journaled inthe frame 12, as shown. The shaft 129 carries' a collar 130 having anotch 131 cut therein, so formed as to be engaged and locked in positionby the rocking latch-lever 132 pivoted to the frame 12 at 133. The lowerend 134 of the latch 132 is so oonstructed and arranged as to be engagedby the rotating lug 135 mounted on the transfer-cylinder 14, when thatcylinder has been displaced and is separated from the formcylinder 13,theconstruction shown in Fig. 8, illustrating this feature intheconstruction with the lug 135 albout to engage the end 134 to trip thelatch 132, to throw off the impression-cylinder 15 by allowing thespring 125 to break the toggle-levers 1251 and 122, to move the link 127to the left and to swing the arm 120 in the direction shown by 'thearrow, to move the eccentric bearings 118, thereby separating thecylinder 15 from its printing relation with the cylinder 14. 1t isobvious that this movement of the eccentric bearings 118 may beaccomplished by av suitable spring coiled about the shaft 129, or by anyother convenient mechanism actuated by the latch-lever 132, throughproper connecting devices.

' The latch-lever 132 may be reset in the notch 131 by the hand-lever136 carrying the lug 137 coacting with the lug 138 on the collar 139mounted on the shaft 124, thereby rotating the shaft 129contra-clockwise, and straightening the toggle-levers 121 and-122, whilesimultaneously placing the spring 125 again under tension. By properlyadjusting and positioning the lugs 61 and 135 Qn the transfer-cylinder14, the successive trip- -ping operations, through the respectiveengagements with the trip-levers 58 and 13,2, can be timed at anyintervals desired, and in either succession. However, it is preferableto so arrange the throw-oifs so as to cause impression ,cylinder -tothrow off before the inking rollers are separated from the'form-cylinder, by making such appropriate changes in the arrangement ofthe trip-levers and their respective coperating lugs mounted on thetransfer-cylinder 1.4, as 'will accomplish these successive movements inthe order desired, all of which will be readily understood by those,skilled in this art.

In Fig. 9'1 have shown a still further variation in the mechanism forsuccessively -throwing-0H the respective cylinders from contact witheach with the other, b'yr'showing both the' transfer-cylinderv 14 Vandthe impression-cylinder 15 mounted and operable in eccentric bearings.1n this constructhe feed vof the stock 37 lon the feed-table 36, f

this initial movement separating only the transfer-cylinder 14 from theform-cylinder 13; the .second eccentric movement is operable by the lugmounted on the transfercylinder 14, now separated from the formcylinder13, engaging with the latch-lever 4 132 to throw off theimpression-cylinder 15 from the transfer-cylinder 14, as has beenheretofore described with relation to the construction shown in Figs. 7and 8. Thereafter the lug -61 trips the rock-lever 58 to release thelatch 66, which controls the operation of the mechanism for throwing,off the inking rollers, as has been already described in connectionwith the construction shown in Figs. 1, 2 and 3. v

It is apparent that the impression-cylinder 15 may be initiallyseparated from the transfer-cylinder 14, in the cycle of operations cfthe press, in which case the lugs 61 and 135 would be suitably mountedupon the impression-cylinder 15, and the respective trip-levermechanisms operable through engagement with these lugs, would be soarranged'in proper relation thereto as to insure the predeterminedsuccession of throwoffs inthe press.

In the embodiments of my invention shown in Figs. 12 and 13, I haveillustrated forms of oflset presses in which, in each case, theactuating lug is mounted on a cylinder which is not aected by theinitial throw-off movement.

In the construction shown in Fig. 12, the transfercylinder 14 is alonemounted and operable in eccentric bearings 19, as shown in Figs. 1, 2and 3. In this form, the eccentric bearings 1,9 are first actuated, asshown in Fig. 2, by the tripping mechanism controlled by the absence orinterruption of the feed of the stock 37 on the feed-table 36, ormanually-operated means may be .used to inaugurate this initialmovement, which separates the transfer-cylinder 14 from bothformcylinder 13 and impression cylinder 15, as already set forth.Mounted on the pin 136 on the outside of the frame 12 is the lever 137,the upper arm of which has the slotted bearing 138 adapted to engagewith the studor pin 139 on the end of the shaft 17. The lower a-rm 140(shown in dotted lines) of the lever 137 is onthe inside of the frame12, and carries, on the pivot 141, the rock-lever 142, theouter end 143of which lever 142 isv adapted to engage the lug 144 mounted on theimpression-cylinder 15 when the lever 137 is oscillated through theseparation of the transfer-cylinder 14 from the other two cylinders 13and 14 just described. The other arm 145 of the lever 142, is connectedby the link 146 to the lever 64, which operates the latch 66 in thenotch 67, to throw` off the inking rollers 52 from the form-cylinder 13,all as has been hereinbefore described in connection with theconstruction and operation of the presses shown in Figs. 1, 2 and 3.

In the construction shown in Fig. 13, the impression-cylinder 15 isalone mounted and operable in eccentric bearings 118, as in the formsshown in Figs. 7, 8 and 9. In this Fig. 13 construction, the eccentricbearings 118 are first operated bythe tripping mechanism heretoforeshown .and described, or by manual means, so as to separate theimpression-cylinder 15 fiom the transfer-cylinder 14. This may beaccomplished by the following mechanism: Mounted on the arm 120 is thetoggle lever 147 pivoted at 148 to the other toggle lever 149, which ispivotally mounted on the pin 150 secured to th'e frame 12. The lever 149is connected by the link 151 to the arm 152 carried on the rockshaft 27.The compression spring 153 is secured between the lever 149 and theframe, and breaks the toggle levers 147 and 149 from their straightenedposition, as shown, to move the arm `120 to the left, whenever the latch31 is released from the notch 34 in the sleeve 35 mounted on the shaft27. Pivoted on the ypin 154 on the outside of the frame 12 is the lever155, Ythe upper arm of which has the slotted bearing 156 adapted to lengage with the stud or pin 157 on the end of the shaft 18. The lowerarm 158 (shown in dotted lines) of the lever 155 is on the inside of theframe 12, and carries on the pivot 159 the rock-lever 160, the outer end161 of which lever 160 is adapted to engage the lug 162 mounted on thetransfer-cylinder 14, when the lever 155 is oscillated through theseparation of the impression-cylinder 15 from the transfer-cylinder 14,as hasv been already described. The other end 163 of the lever 160 isconnected by the link 164 to the lever 64 which operates the latch 66 inthe notch 67 to throw off the inking rollers 52 from the form-cylinder,all as has been already set forth in connection with Figs. l, 2 and 3.

The foregoing constructions all embody the principles of my invention asapplied to off-set presses, but it is obvious that my invention isapplicable to other forms of printing-presses, and that othercombinations and modes of operation may be made; the foregoing beingsuflicient to disclose the underlying principles and advantagesinvolved. The actuating lugs or other engaging members are preferablydisposed and mounted on the different coacting printing membersconstituting the press, yet they may be arranged and operable upon otherparts of the press, so as to insure the predetermined sequence ofoperations desired, so long as they are disposed to be thrown into thepath of some intermediate device, the operation of which is controlledand inaugurated by the initial movement in the press.
